To all whom (it may concern:

Be it known that I, J AMES W. KENNEUY, -a subject ofthe King of'GreatBritain, and a resident of Chicago, in vthe, county bf Cook` and Stateof Illinois, have inv'entedfl certain new'j and useful Improvements' in'Ribbon Mechanism for Type-Writing Machines, yof which the following'isa speciication.

This invention relatesto ribbon mechan# ism for typewriting machines. yy f In typewriting machines it frequently hap- `pens that it is desiredto do diiferen't kinds of. work, either -workof diierentcolors or recordand copying. Se far as .I am aware,

this has heretofore been' effected by; the useA of a single ribboncomprising ,distinct por-.

tions of different character, either of diiferent colors or partV recordand part copying,vv

which extend lengthwise ofthe ribbon, each occupying its appropriate,portion of the widt of the ribbon and the. different kinds of workbeing secured by shifting the ribbon dilierent distancesfsothat oneportion or the other thereof will overlie the platen and be presentedtothe type in the operation of the machine. as may be desired. Thisconstrue tion and method of operation is objection able, first,becauseowin 'to the limitation as to the width of the ribbon, the differentVportions of the ribbons are so narrow -that the mechanism hasv to be sofine and deli. cately adjusted that itlis practicallyimpossible tosecure reliable results, in operation, often resulting in ,confusion`ofthe different characters .of work and thus defeating the very objectsought to bey attained; isecond, because, due to the fact .that onecharacter `of print is used much more. thanthe other,

lone portion of ther ribbon is worn out long before the other, thusnecessitating replacln the entire ribbon while aportion of it is stigoed and` consequently resultingin loss'l to the user ;v third, duetothe narrowness'of the different portions of' the ribbon; it isimpossible to provide any lateral traverse thereto in operation so thatthe typealways strike strike at different points transversely of theconsumption of ink,

The primary obiect of my .invention is to overcome. these objectionablefeatures and I ribbon, distributing both the wear and 'the attain thisresult by providing separate rib-.lv

" bons for the diHerentcharacters of work desiredin connection withoperating and con.-

trolling mec anism, whereby, as the inachlne 1s operated, either ribbon'mechanism lmay be released and actuated so ,that theI ribboncontrolled' thereby will receive theV irripr'ession and the other willbe`disengaged and locked against operation, thereby ermltting the use ofribbons of standard width and securing' and insuring uniformity ofoperation under allv conditions.l

The invention also'consists of the yvarious other features, combinationsof features and details of construction hereinafter described In theaccompanying drawings, in'whichv my invention is fullyillustrated,-Figure 1 `2%-,-3 of Fig. 1. Fig'. 4 is a partial sectionalelevation on an enlarged scale, taken` ap'- proximately on the line 4-4-of Fig. V3.' Fig.

Fig. 7 is a partial enlarged sectional view onthe line 7-Z of Fig. 5. Figs. S and 9 are, respectively, an enlargedside elevation and a vertical 'sectional View of one of the ribbon Fig.3 is a rear sectional elevation of the machine, on the line spools. 1Fig. 10 is a 'detail sectional view on the line 10--10 of Figf5.

Fig. 12'is a'detail view of a portion of the front of the machine showing anindicator plate in connection with 'the shift lever for convenyientlyand correctly indicating the character of the work for which the machineis set at any ti'me;and Fig. 13 is an isometric view sho-wing the meansfor supporting the ribbon `bobbers in normal or depressed positions. i

For purposes of concrete illustration, I have,in the accompanyingdrawings, shown my improved ribbon mechanism as applied to or embodiedin a typewriting machine of 'the kind known, commercially, as theUnderwood typewriter. As regards its 'usual lfeatures, the constructionand operation of said machine is familiar to most persons skilledin thetypewriter art and will require no extended detailed descriptionthereof.

For purposes ofreference, various parts of 4the machine are' designatedin fthe drawings as Vfollows :#A, the' 'fr am`e` of the machme, B,

.the platen7 Bf the platen c'arriage,'C the disk 1in which the typebars()1 are pivoted, D the universal bar connected to therocker rod D1.by the arms d and the skeleton plate d, E the keys, E1` the lteylevers,F thespace bar,

-now'deseribe my improved ribbon Ribbons 1 and 2 oiudiiferentcharacter,as a 1-G0Td.1`ibbon and a copying ribbon or diff-if ferent coloredribbons, -are'Wound on separate .l spools 3;,and l secured to rotateWith jvert'ically dis osed sha-its 5 revolubly mounted .in suitableearings at opposite sides of the mav "chine and towhich step bysteprotation is imparted, jas fthe machine is. operated, by

:means 'of suitable driving connection with the feed*ratehetsG.;-v Asshown,- said spools Siand 4 are-,secured to the-shafts 5, so that.-

they can' be `quicklyand conveniently removed therefrom, in'thefollowing manner Secured-.to the shafts 5 at a point to deiine'the'vproper positions, .vertically, ofi said4 .spools 3 and 4, arecollars 1G, secured inwhich i are pins 7 adapted to engagecorrespond-ing holes inthe lower spool and, in like manner,

" `pinfs securedin theloWei: spoolare adapted to engage holesin the` nperspool.l -Wi-th` `this.c on'struction itv iso vious that both 'spoolsWill be secured to the shaft 5 and may,

at Vthe Sametime be lifted off fromL-the'same Whenever itI is 'desiredto remove them.

'i The vspools 3 and 4f are inclos'ed -in fixed casingls 9, whichareopen at the top to permit eremoval of the spools and Whiohanevprovided with suitable one-for .each ribbon.

Wh re `the ribbon -doesnotpassstraight between its spools, as is thecasepwith thev ylov'vfer ribbon 'in the'drawings, the sides of the'construction and dll 'be readily understood Hat bO guide slotsl-legainst which the ribbons' bear are referably i 'arranged onedirectly vin iront ofthe other.

As regardsV theirusual-features, said ribbon'.

bobbers may-.be of anydesired or. approved by-vthoserfamiliar with theartffrom an in'e spection ofthe drawings without aldetaileddescrlpt'ion; thereof. As shown, saidribbon bobbers jare, guided intheir. vertical movelan towards opposite sides lto'bring the same indesired .relation `to' parts ofA the mechanlsmom lower to" guide slots10'and`1 1,

nient by `means lof 'clips 14 thereon which re-A spectively engage theAedges, of the type bar guide 15 vand of a piece 16 secured to themachine irame and by screws'. 17 which engage i suitable guide slots indownward extensions 1 8 and 1) ci said ribbon bobbels 12, and 13, resectively, said downward extensions 1S 19- of said ribbon bobbers beingoiisetv Which engage the same for operation` In 'order that, inoperation, the ribbon bobbers and the ribbons respec'tively cai"- riedthereby may not catch upon each other and thusiinteriere With theirdesigned opera tion, said! ribbon bobbersare norinallyheld apart.. bymeans of springs 2O, which, as shown, are secured to the ribben bobber12 and bear against the adjacent .side ot' the bobbe'r '13, as bestshovmin Fig. '6.

Y. When vin normal or depressed position, the

lowerend's of the downward extensions 1S and-l9 of the ribbon bobbers 12and 13 rest and are supported upon the upper ends of arms 21 and 22formed on a plate 22 carried by the platen-frame supporting bar H, asclearly shown in Fig. 4 of the drawings. Said plate 23, being carried bythe platen supporting rodvH, it is obvious that, when',y

said rod His raised or lowered in order to shlft fromlower to upper caseor vice versa,

said plate 23- Will be correspondingly raised or i ,.loWered,thusmaintaining the ribbon bobbers .in proper operative vpositionrelatively to the platen. In the type of machine shown in' the drawings,however, the platen sup.

porting frame is pivoted to the carriage at a -pomt in therearlof saidlplaten,'so thati`n shifting, the platen will move'on the arofof a.

circle, and the plate 23,- on which the bobber supporting arms 2'1 and22.are formed, being los carried by the: platen frame supporting rod H-and extending afconsider'able distaneein ffront'thereof, will travelthrough a considerably longer are than the platen which' would' .bringthe ribbons land 2 into improper rela'- tion' to said platen. To'prevent this, said ,plate 23, instead of beingr rigidly secured to .theplaten supportingT rod H', is hinged to a platel24 on said rod. When atthelovrer :limit of its movement, the plate 23 isl maintained inloperative position by means of rigid stops consistinbg, as shown, ofscrews`25 threaded through the upper end of an arm'26 rigidly secured tothe frame ofthe machine, f

With this con as clearly shown -in Fig. 2'.

struction it is-obvious that, when 'said plate j 23 is in depressedposition the ends of the .arms .211 and -22 which support the ribbonbobbers maybe adjusted vertically by ,means of the stop screws 25, whichthus provide eonvenient means foradjusting the position of the ribbonbobbers to bring the same into proper operative relation to the platenWhen in its depressed position. When the platen supporting rod H israised to shift the platen, the plate 23 passes out of contact with the`stop screws 25 and is maintained in. operative position 'by means o'ila stop linger 27 on the plate 24, which extends downwardly so as tobear aUainst the rear side of the plate 23. Whilev the Weight of theplate 23 and of the parts carried thereby would doubtless be sutiicientto hold said plate at the lower limit of its pivotal movement, asdefined either-by the stop screws' 25 or the stop'nge'r 27, I prefer tospplen'vent th-e gravity of the parts by means of'a-s ring 28 secured tosaid plate 23 and whic lbears against the rear side of the stopfinger27. Said stop finger27 is sopositlonedfthat, when the platensupporting rod H` is inA raised position, said stop iinger 'Will supporttheA plate 23 in position to bring the ribbon bobbers. in properoperative position relatively to the platen, while, by .adjusting thestop screws 25 so that they will contact. vfith the rear side of theplate 23 at a proper pointA before the rodor rbarH reaches its lowermostposition, said plate will be swung on itshinge a su iticient distance tocompensate for-thedifference between the travel of the platen and of thearms 21 and 2,2 to bring .the ribbon bobbers in proper opera-tiveposition ,rela- 30' tively to the platen when iii-lowered or lde,-

pressed position. .The stop screws 25may position byA be secured-indesiredadjusted means of suitable lock nu-ts thereon..

, Formed in the lower ends of the, downward I extensions-18 and 19 ofthe ribbon 'b'o-bber's,v

are holes or o enings 30, which, as shown," are formed 'by ending theends o'f 'said downward extensions 18 and 19 into theform of, loops.,the lower flat sides of which are'adapt-4 ed to rest upor the upperendsof'the-arms21 and 22. The-loops orheles 30 are adapted to be engagedby catches 31-onaslide'32 mounted, so' as -to .be transversely movable,

In-

order that the jar incidentto lthe operation of the machine may notcause the `slide 32 to c5' shift accidentally,v I provide a spring catchatthe upper ends of the yarms 2,1 and 22,'as

l33 adapted, to engage suitable notches 34 lplat en -frame'supportingbar H, desired pivotal movement beine;- imparted to'said lever by' meansof a stud 37 thereon which engages a vertical slot 38 vformed in abracket 39 car. ried on the, plate d1' connected with the universal barD.- l 'Ihe'fr'ont-end of the lever 35 extends between the arms 20 and 21ofthe plate 23 and mounted in suitable bearings in guide flugs 40thereonso asto' be transversely mov- "able, is a locking pin .41 which isadapted to enter Athe holes lor loops 30 in the lower ends of theribbon. bobb-ers as said pin is moved in one direction or the other,thus locking one or lthe other of said ribbon bobbers to said lever35t'h'e length ofthe locking pin 41being such that when said locking pinIsin engagement with the `vhole or loo i 30 .in one of said ribbonbobbers it' wil-lbe disengaged from the other.4 i,
